Answer:
Eva
Step-by-step explanation:
If 4 dollar = 440 yen
Therefore, 1 dollar = (440 ÷ 4) yen
1 dollar = 110 yen
As Eva is saving 52 dollars per week, and Ryu is saving 5,500 yen per week, we have to convert dollar into yen to find who has saved more.
1 dollar = 110 yen
52 dollar = (52 × 110) = 5720 yen
It means Eva is saving 52 dollar which is equivalent to 5,700 yens. It is more than Ryu's saving account.
